In response I get an ID that identifies a newly created web map.
Quite often i need to update both map definition and associated feature service content, but once I obtain a webmap ID and i send it to other users in my organisation i would like to be able to update content under that webmap ID rather than regenerate it every time. Is it possible to enforce specific webmap ID generation? Or update a webmap under certain webmapID?
I perform the whole process of web map publishing using arcpy.
